Definitions

  • the present invention relates to bread makers and to driving mechanisms, and more particularly, but not exclusively, to bread makers having an improved driving force transmission structure.
  • a bread maker disclosed in Korean Patent Publication No. 1991-10203 includes a pair of parallel kneading drums which are disposed at upper and lower parts of an oven compartment and rotated in clockwise and counterclockwise directions; a baking tray placed between the pair of kneading drums; and a heater to heat the inside of the oven compartment.
  • opposite ends of a mixing bag filled with raw materials for bread are wound by the pair of the kneading drums and then the mixing bag is reciprocated up and down for a predetermined period of time, so that the raw materials for bread in the mixing bag are kneaded.
  • a cutting unit cuts the mixing bag, so that only the kneaded dough moves into the baking tray. Then, the heater heats the interior of the oven compartment, making bread in the baking tray by leavening and baking the dough for a predetermined period of time.
  • a reversible type motor rotates the pair of kneading drums reciprocating the mixing bag up and down.
  • the mechanism for transmitting the driving force generated by the motor to the kneading drums needs to be efficiently designed for high productivity in such a way that each part thereof can be easily replaced so as to reduce assembling process time.
  • the present invention provides a bread maker comprising: a main body divided into an oven compartment and a component compartment; upper and lower kneading drums which are rotatably provided at upper and lower parts inside of the oven compartment to wind opposite ends of a mixing bag filled with raw materials for bread; and a drum driving part placed in the component compartment to rotate the upper and lower kneading drums, the drum driving part including: a driving motor generating a driving force to rotate the lower kneading drum; a reduction gear which speed-reduces the driving force of the driving motor and has an output shaft thereof transmitting the speed-reduced driving force to the lower kneading drum; a connector connecting the output shaft and the lower kneading drum; upper and lower pulleys rotatably connected to the upper and lower kneading drums, respectively; and a driving belt connected to the upper and lower pulleys to rotate the upper and lower kneading drums, wherein one
  • the engager includes a plurality of engaging projections projected in a radial direction relative to the axis of the output shaft on an outer surface of the connector; and a plurality of projections accommodating grooves formed in the lower pulley to accommodate the engaging projections.
  • three engaging projections are uniformly distributed on the outer surface of the connector.
  • the reduction gear includes a worm connected to the shaft of the driving motor and a worm wheel engaged with the worm, and a gear case accommodating the worm and the worm wheel.
  • a bread maker of an embodiment of the present invention comprises: a main body 1 divided into an oven compartment 10 and a component compartment 5, a door 3 in the front of the main body 1 to open and close a front opening of the oven compartment 10; and an operation display panel (not shown) on a front side of the main body 1 to display an operation state of the main body 1.
  • upper and lower kneading drums 11 and 13 which are rotatably disposed in parallel to wind a predetermined length of opposite ends of a mixing bag (not shown), filled with raw materials for making bread, in clockwise and counterclockwise directions.
  • a baking tray 15 containing kneaded materials therein is provided between the upper and lower kneading drums 11 and 13.
  • a pair of dough-blocking members 17 preventing the raw materials kneaded in the mixing bag from being moved toward the upper kneading drum 11.
  • Each of the kneading drums comprises: a drum main body 40 which is formed along a longitudinal direction thereof with a plurality of holding projections (not shown) to be inserted in holding holes (not shown) formed at end parts of the mixing bag; the driving shaft part 41 which is extended outward from one end of the drum main body 40 and is rotatably supported on a wall of a first component compartment 21 (to be described later); and a supporting shaft part (not shown) which is extended outward from the other end of the drum main body 40 and is supported on the inner wall of the oven compartment 10 on the opposite side of the wall supporting the driving shaft part 41 so as to be rotated in clockwise and counterclockwise directions.
  • the baking tray 15 forms a box having a top opening by combining first and second trays 15a and 15b of "L" shapes symmetrical to each other.
  • baking heaters 19 are provided to heat the inside of the oven compartment 10.
  • the component compartment 5 includes the first component compartment 21 beside the oven compartment 10 and a second component compartment 23 behind the oven compartment 10. Inside the first component compartment 21 is placed a drum driving part (to be described later) rotating the upper and lower kneading drums 11 and 13 in clockwise and counterclockwise directions.
  • the drum driving part comprises: a driving motor 26 to rotate the lower kneading drum 13; a reduction gear 50 reducing the number of rotations of the driving motor 26; a connector 60 connecting an output shaft 55 of the reduction gear 50 and the driving shaft part 41 of the lower kneading drum 13; upper and lower pulleys 70 and 71 rotatably connected to the driving shaft parts 41 of the upper and lower kneading drums 11 and 13; and a driving belt 80 which is connected to the pair of pulleys 70 and 71 and rotates the upper and lower kneading drums 11 and 13.
  • a driving force generated by the driving motor 26 is used to rotate the lower kneading drum 13 and transmitted to the driving shaft part 41 of the lower kneading drum 13 connected to the output shaft 55 and the connector 60 by means of the reduction gear 50 located in the lower part of the driving motor 26.
  • the reduction gear 50 comprises a worm gear set having a worm 53 and a worm wheel 54 in a gear case 51 located under the driving motor 26 and accommodating the worm gear set.
  • the worm 53 is connected to the end of the shaft 52 of the driving motor 26 and the worm wheel 54 is connected to the output shaft 55, which in turn is connected to the driving shaft part 41 of the lower kneading drum 13 by the connector 60 and is engaged with the worm 53.
  • One side of the connector 60 is connected to the output shaft 55 having the worm wheel 54 and the other side thereof is connected to the lower pulley 71 rotatably connected to the driving shaft part 41 of the lower kneading drum 13.
  • the connector 60 transmits the driving force from the motor 26 via the reduction gear 50 to the lower kneading drum 13.
  • the engager includes a plurality of engaging projections 90 projected in a radial direction on an outer surface side of the connector 60; and a plurality of projections accommodating grooves 91 provided at a corresponding position of the lower pulley 71 to accommodate the engaging projections 90 of the connector 60.
  • the engaging projections 90 are projected in a radial direction relative to the axis of the output shaft 55 on the outer surface of the connector 60. As shown in FIG. 3, three equally spaced engaging projections 90 are projected on the outer surface of the connector 60.
  • the projections accommodating grooves 91 of the lower pulley 71 are distributed in a radial direction relative to the axis of the output shaft 55, matching the number of engaging projections 90.
  • the speed-reduced driving force is responsible for rotating the lower kneading drum 13 as well as the upper kneading drum 11 connected to the lower kneading drum 13 by the transmitting belt 80.
  • the connector 60 and the lower pulley 71 can be coupled with much ease only by accommodating the engaging projections 90 of the connector 60 in the projections accommodating grooves 91 of the lower pulley 71. This guarantees that the driving force generated by the driving motor 26 is transmitted to the lower kneading drum 13, even if the connector 60 and the lower pulley 71 are not assembled at the exact assembling positions. This saves time and effort assembling the connector 60 and the lower pulley 71, and further the bread maker as a whole.
  • the driving force of the driving motor can be smoothly transmitted to the lower kneading drum, thereby providing increased productivity by reducing time taken for assembling the bread maker.
